GENERATOR FOR GAS-ENGINES.

SPECIFICATION forming part of Letters-gIPatent No. 734,986, dated July 28, 1903.

Application filed June 23,1902. Serial No. 112,929. (Nn model.-

To all whom it puny concern:

Be it known that I, JOHN MARTIN STADEL, a citizen of the United States of America, and a resident of IVilmingtom'in the county of Newcastle and State of Delaware, have invented certain new and useful Improvements in Generators for Gas-Engines, of which the following is a specification.

This invention relates to certain new and 1o useful improvements in generators for converting gasolene into gas previous to its being used in a gas-engine; and the object of my invention is to provide a simple generator of inexpensive construction which can be used r 5 without the danger usually incident to such purposes.

In its preferred form my generator consists of a chamber in which the gasolene is fed, and surrounding this chamber is a water-jacket zo into which hot water is circulated for the purpose of maintaining` the atmosphere at such a temperature as will generate a gas as fast as the gasolene is fed into the generator. The generator is also provided with a springactuated cap or cover, which is arranged to automatically open and permit the escape of the gas in the event of too much gasbeiug generated.

Having in view a generator of the general 3o class above described, my invention consists in the peculiar construction, arrangement, and combinations of parts, ashereinafter more particularly described and then definitely claimed.

The accompanying drawingrepresents a.

vertical central section of a generator constructed in accordance with my invention.

Referring now to the details of the said drawing by numerals, l represents a suit- 4o able receptacle, which may be supported on a base of any desirable construction, but preferably of the shape shown in the drawing, which consists of a cylindrical shell 2, with a supporting-ring 3 at the upper end thereof, and a basediange 4, by which the base may loe secured to any suitable support.

Surrounding the receptacle l is a waterjacket 5, which is preferably open at the top, and entering this water-jacket 5 is an inlet 6 5o and an outlet 7, by which hot water may be delivered and taken from the jacket, thus insuring rapid circulation.

It will be evident from'the construction so far described that if gasolene is fed into the generator and hot water is fed to the inlet 6 55 the temperature within the receptacle or generator l may be maintained sufficiently high to generate a gas as fast as the gasolene is fed into the receptacle. Underneath the receptacle l I have shown a burner 7, which may be 6o used in lieu of or supplemental to the jacket 5, as circumstances require.

Fitting within the upper end of the generator or receptacle l isa hoodv or cover 8, which has a downwardly-extending ring or flange 9, closely tting the walls of the generator l. The hood or cover 8 also has a horizontallyextending flange 9 to iit over the upper edge of the walls of the generator or receptacle l. The downwardly-projecting ring or flange 9 7o is provided with escape-openings ll, which are normally covered by th'evw'alls of the receptacle or generator l. Y

Secured to the upper edge of the generating-chamberl, on each side thereof, are brackets l2 and 13, which are slotted or recessed to receive the bent ends la of a yoke 15, which is provided with an opening immediately over the center of the generator. The hood or cover 8 is also, provided with ascrew- 8o threaded opening immediately under and in line with the opening in the yoke, and a screw-threaded tube vlSfpasses through the opening in the yoke l5 andy is screwed in the screw-threaded aperture iin/the hood or cover 8,' as yillustrated in the drawing. Interposed between the swelled portion of the hood or cover 8 and the yoke l5 andsurroundin g the tube 18 is a stiff coiled spring 2Q, which tends to retain the hood or coverL 8,v in its closed po- 9o sition, as shown in the drawingf This construction is for the purpose of ,insuring safety at all times no vmatter how' much gas maybe generated Within the receptacle l, and-it is obvious that if too much gas is generated within the receptacle and the pressure becomes so great as to overcome the tensionof the spring 2O the hood or cover --S will. be forced upward until the escape-openings ll are exposed, when the gas can escape until roo the pressure is decreased, so that the spring 2O will force the cover S down into its usual position.

I have illustrated and described no means for feeding gasolene into the generatingchamber or for delivering the gas therefrom; but it will be obvious that suitable provision for feeding' the gasolene and for delivering the gas may be made at any place in the generating-chamber, although I prefer that the gasolene pass through and the gas be delivered from the tube 18.

I have illustrated both a water-jacket and a burner for maintaining' a sufficiently high temperature to generate the gas; but it is obvious that either of these may be dispensed with, as in some situations it maybe diflicult to provide hot water, in which case the burner may be used. I do not, however, limit my invention to either one of these, as parts thereof may be used with both heating' appliances or with either one.

At the lower end of Jthe generating-chamber I'have provided a cock 22, by which the generator may be cleaned out in case of necessity. y

I am aware that it has heretofore been proposed to connect an ordinary safety-valve to the top of a generating-chamber and do not attempt to claim this as my invention, as I regard my construction as entirely different therefrom and have therefore set forth in most of my claims a hood or cover, which I regard as differentiating my invention from the prior art. Of course I do7 not mean by th is term to limit my claims to a vessel having' a hood or cover covering the entire head of the generator, as it is obvious that the cover can be made smaller, it' so desired.

That I claim as new is l. A generating-chamber having means for heating the same, and a hood or cover arranged to open in case of excessive generation, substantially as described.

2. A generating-chamber having means for heating the same, and a spring-actuated cap or cover arranged to open in case of excessive generation, substantially as described.

3. In a generator, the combination of a generating-chamber, a hood or cover therefor, and a spring tending to maintain said cover in its closed position, substantially as described.

4. In a generator, the combination of a generating-chamber, a hood or cover therefor having a projecting ring or iiange provided with escape-openings, and a spring for maintaining said cover in `its closed position, substantially as described.

5. In a generator, the combination of a generating-chamber having a waterjacket for heating the same, a hood or cover for said chamber, and a spring tending to maintain said cover in its closed position,l substantially as described.

6. In a generator, the combination of a generating-chamber having a water-jacket for heating the same, a hood or cover for said chamber having a projecting ring or flange provided with escape-openings and a spring for maintaining said hood or cover in its closed position, substantially as described.

7. In a generator, the combination of a generating-chamber arranged with means for heating the same, a hood or cover for said chamber having a projecting ring or flange provided with escape-openings, a yoke having a connection with said generating-chamber and extending over said hood or cover, and a spring arranged between said yoke and said hood or cover, for maintaining said cover in its closed position, substantially as described.

S. In a generator, the combination of a generating-chamber, having a Water-jacket surrounding the same, a hood or cover for said chamber having a projecting ring or Yflange provided with escape-openings, a yoke having a connection with said chamber and extending over said hood or cover, and a spring interposed between said yoke and said hood or cover for maintaining said hood or cover in position, substantially as described.

9. A generating-chamber having means for heating the same, and a device arranged to open in case of excessive generation, the said device also acting as a means of supplying the gas delivered from the said chamber, substantially as described.

Signed by me at filmington this 2d day of June, 1902.
